I have nine hens and two roosters ( old silkie and a newbie miniature sussex ) I have the sussex only six days. This morning when i opened the shed door Peach my oprington ran out, she is starting to get bare patches on her neck and back. I dont think its the sussex because he is still new and Peach intimidates him and chases him away, but it looks too close together to be from the bigger silkie roo. I really dont want to cull either of them. What can i do to stop this? I plan to buy two pullets tomorrow if that helps ease it im not sure :/ How many hens should you have per rooster? Thanks
